  1. Identify the name of the FLEXlm license server host

  2. On the client machine, stop ClearCase

  3. Copy the flexlm_host.template file (located in one of the following directories) to the /var/adm/rational/clearcase/config directory
    • /opt/rational/clearcase/config/rcl/flexlm_host.template
    • /opt/IBM/rational/clearcase/config/rcl/flexlm_host.template
    • /opt/IBM/RationalSDLC/clearcase/config/rcl/flexlm_host.template

  4. Rename the flexlm_host.template file to flexlm_host

  5. Verify that this file has read access for all users
